Hi,I was learning RBD constraint recently and I know how to use conetwist constraint for simple object such as a door
but I am confuse parameters on rbdconetwistconstraintproperties sop. such as what is the different about Goal Twist Axis vs Constrainted Twist Axis? is there a detail example or tutorial about it ?

How to create a slide constraint in the SOP RBD workflow, as there are no relevant SOP nodes

1. you enable it in solvers Advanced tab
2. add relevant constraint attributes [www.sidefx.com] to your constraint prims including s@constraint_name = "Slider", or whatever you name it in the Advanced tab

Thank you very much

In 20.5 the conetwist constraints were updated with position ranges, stiffness etc. This means the conetwist constraints can now do everything the slider constraints can do and more. The RBD Cone Twist Constraint Properties SOP should allow you to interactively tweak them to get the results you're after in a much more intuitive way.

Thank you for your confirm, It help me a lot.
